Munir Mohammed began buying chemicals for a homemade pressure cooker bomb and offered himself as a “lone wolf” attacker to an IS commander communicating with him over Facebook.

He also investigated making poison while working at a supermarket ready-meals factory.

The Islamic State group used prisoners as “human guinea pigs,” carrying out chemical weapons experiments in order to plan for attacks against the West, documents found in Mosul have revealed. The papers detailing the tests, which led to the agonizing deaths of prisoners, were discovered at Mosul University in January when it was recaptured by Iraqi special forces.

Prisoners had their food and water contaminated by the sprinkling of chemicals found in easily accessible pesticides. The U.S. and Britain now fear that the same methods could be used on a larger scale to contaminate food supplies in the West.

In one of the experiments detailed, a man was gradually poisoned with thallium sulfate, a colorless, tasteless toxin made famous by the Agatha Christie mystery, The Pale Horse. ISIS described it as an “ideal lethal poison” and its test subject, having been given it over a period of 10 days, suffered nausea, fever, swelling of his stomach and brain and eventually an excruciating death.

The Department of Homeland Security has issued a warning raising concern about the vulnerability of the U.S. food and beverage supply chains.

“While we have not seen any specific, credible terrorist threats against Homeland food production and distribution infrastructure, we cannot rule out the possibility of inspired violent extremists or disgruntled insiders attempting to adulterate or poison food and beverages,” DHS said, according to a roll call bulletin for police, fire/EMS and security personnel issued on May 27 2017.

According to the alert, “a South African farmworker in early 2017 added 20 liters of gramoxone — a dipyridinium-based herbicide — to a milk storage tank. While the contamination was detected prior to distribution, the level of gramoxone was likely sufficient to have killed or sickened at least hundreds of people.

In another case, a Nigerian man allegedly introduced an unknown poison into the food at a restaurant in Ogoja, Nigeria, in late March 2017, killing two and sickening 40 others.Closer to home, an offshoot of Greek environmental terrorist groups, Combative Anarchy/Informal Anarchist Federation, “threatened to poison food and beverages made by Nestle, Unilever, Delta Foods, and a named U.S. business in late 2016, leading to mass recalls,” said the bulletin.

In 2010, a plot uncovered is said to involve the use of two poisons – ricin and cyanide – slipped into salad bars and buffets. Of particular concern: The plotters are believed to be tied to the same terror group that attempted to blow up cargo planes over the east coast in October, al Qaeda in the Arabian Peninsula.
